Download management system

Abstract

A download management system includes a server, a computer host and a storage device. The server stores an encrypted data, which is encrypted according to a certification signature. The computer host is communicatively connected to the server for executing a management program. The storage device is connected electrically to the computer host and includes the certification signature, wherein the download management execution program is capable of reading the certification signature from the storage device, downloading the encrypted data from the server, decrypings the encrypted data according to the certification signature to obtain a decrypted data, and storing the decrypted data in the storage device.

1 . A download management system comprising:
 a server storing at least an encrypted data, the encrypted data being encrypted according to at least a certification signature;   a computer host communicatively connected to the server for executing a download management execution program; and   a storage device connected electrically to the computer host, and including the certification signature;   wherein, the download management execution program is adapted to read out the certification signature from the storage device, download the encrypted data from the server, decrypt the encrypted data into a decrypted data according to the certification signature, and store the decrypted data in the storage device.   
     
     
         2 . The download management system according to  claim 1 , wherein the encrypted data is derived from transferring the decrypted data according to an encrypt/decrypt conversion table, and the encrypt/decrypt conversion table is generated by transferring the certification signature via a preset random number generator. 
     
     
         3 . The download management system according to  claim 1 , wherein the decrypted data is derived from transferring the encrypted data according to an encrypt/decrypt conversion table, and the encrypt/decrypt conversion table is generated by transferring the certification signature via a preset random number generator. 
     
     
         4 . The download management system according to  claim 1 , wherein the certification signature is selected from the group of a product identifier (PID) and a vendor identifier (VID). 
     
     
         5 . The download management system according to  claim 1 , wherein the storage device further includes a first storage area and a second storage area, the encrypted data including a storage location note, after the download management execution program obtaining the decrypted data by decrypting the encrypted data, the download management execution program storing the decrypted data in the group of the first storage area and the second storage area according to the storage location note. 
     
     
         6 . The download management system according to  claim 1 , wherein the server further includes a certification unit, the download management execution program sending the certification signature read out from the storage device to the server for the certification unit to certify before the download management execution program downloading the encrypted data.
